Description

The brunch ratios of D→ π l v-tilde(l=e, μ) decay is researched by light cone QCD sum rules. By calculating the form factor fDπ+ (q2)and fDπ (q2) of D→ π, we consider the effect of the lepton mass on the branching rations of the D→π e v-tildee, D→π μ v-tildeμ decay.The brunch ratios are consistent with the experimental data.
